The 4L80E is often considered one of the strongest four-speed automatics on the market. Similar to the ubiquitous TH400, the 4L80E was available in 3/4- and 1-ton trucks and 4x4s, usually behind gas V-8 engines. Bowtie offers rebuilt, and tested transmissions and can ship them straight to your door. Bowtie has just developed a new division known as Maximum Off Road Racing Transmissions that specializes in transmissions from rockcrawlers to Trophy Trucks.
